Questionable performance

[SK91no]

For a project that statically recompiled the game code into x86 it sure is CPU heavy

For reference I run an i7-9750h (and a quadro t1000 but that's less important) which is a mid-high end laptop CPU from 2019
it pegs one core a lot, but even so it's running a 24 year old game so it should be eating it for breakfast, I get that compiling things for modern targets somehow makes things run like 5x slower for some reason but I didn't think it'd be like this
I can't imagine what kind of CPU you'd need to go online abusing the game state, must be pretty beastly.

As I can find with Dolphin, even running it with just one core provides quite a playable result

Meanwhile RingOut comes out more like this

I tried running it on linux too with the ideal building conditions and it ran about the same, maybe even slightly worse

Sorry about the snark

this is what you get with a slopcoded recomp without a competent programmer at the helm

No need to apologise for the snark — the criticism is valid, and I'd rather agree with it than argue.

You're right, and I should have optimised this further before releasing it. A static recompile ought to be the fast path, and "it beats Dolphin because the guest code is native x86" is the claim this project implicitly makes. On your machine it isn't holding up, and a mid-high-end 2019 laptop CPU is not an unreasonable bar for a 2002 console game. That's on me, not on your hardware.

I'm not going to hand you a cause or a date off the back of a screenshot. What I will do is treat performance as work that still needs doing rather than something already finished, and take the Dolphin comparison as the standard to beat rather than a detail.

Thanks for the two screenshots and the CPU model — that's more to go on than "it runs badly", and it's the kind of report I can actually act on.

dude is genuinely slopgenerating his responses too claude codes AND speaks for him 💀

Yeah, the performance isn't ideal. Tried both US raw image and the Plus version mod pre-patched ISO... which I want to inform that it works. Happy to say that. It's a great mod.

But both perform roughly when a match starts... I have a Strix Halo AMD APU with a vast amount of Memory Bandwidth that doesn't have any problems running Gamecube/Wii emulationat all.

But this Recomp goes from 59-60 FPS to the 50s and below 50s... like around the 44FPS framerates at the start of a moving match.

So more work needs to be done, which I'm looking forward to long term. Great work and hope to see more. Would be great if this becomes the plug & play standard of the game + netplay + Plus mod in the future that people can enjoy hassle free. lol!

This is just a pisspoor dolphin exe wrapped as a static recomp. You can just go and play it on the Dolphin with all the goods and graces. Genuinely, what even is this project.

I'm just curious about the rollback atp, HD version has better widescreen implementation at the moment anyway

[jackpoison-prog]

Sorry, everyone. I'm aware now how bad the performance is. Reports like Xorathmion's, 60 dropping to the mid 40s once a match gets going on hardware that runs Dolphin without trouble, make it hard to argue otherwise.

Right now my full focus is on getting it to a respectable place. No other features until that's done. The next release should already be noticeably lighter on the CPU, but it won't be the end of it. I'll post here as it improves.

@SK91no: no rollback yet. Netplay is delay-based for now.

Oh I see, I thought it was rollback for some reason. Looking forward to see how it improves

1.6.2 is out: https://github.com/jackpoison-prog/RingOut/releases/tag/v1.6.2

This is the release I said I'd post about. Every disc version now gets the full set of recompiler optimisations — before, only some of them applied, and only to the US disc. Measured over identical work, it's roughly a third less CPU time on every disc.

Please give it a go and tell me how it lands.

One thing that matters: re-run setup rather than copying the new files over an old install, or you won't see the gain — it's in the module built on your machine. Replays recorded on older versions won't play back either, because emulation timing shifts slightly; the build tells you instead of drifting silently.

If it's still short of 60 for you, say so and include your CPU and distro — that's what makes these quick to chase down.

I'm not finished with this. I'll keep looking for ways to make it run faster.

[Xorathmion]

Happy to report from testing 1.6.2 with both Vanilla US SC2 and SC2 Plus, that it runs really well now... at around 59-60FPS consistently in multiple matches in motion + all kinds of different stages.

The only drops I've seen, which it's not a big deal, is at the loading screen when the character 3D busts show up on the versus screen right before the match loads... sometimes you get like a second or 2 frame drop down to 40FPS but then immediately back up to 59-60FPS.

But the matches are and feel pretty good, yet to try the netplay with anyone but from my offline experience... it's great! Better than the 1.6.1. release.

Keep up the good work. Cheers!
